On September 10, 2026, GitLab released patches for critical vulnerabilities CVE-2026-85706 and CVE-2026-87719. CVE-2026-85706, a path traversal flaw, allows unauthenticated users to read arbitrary files from GitLab servers, while CVE-2026-87719 enables credential theft via insecure deserialization. Both vulnerabilities affect GitLab Community Edition (CE) and Enterprise Edition (EE) versions from 18.7 up to 19.3.2.
